On Tuesday, Uber launched a campaign called "180 Days of Change", pledging to make improvements for the next six months.

The company is trying to burnish an image tarnished by revelations of sexual harassment and other bad behavior in its office, as well as allegations of trade secrets theft and an investigation into its efforts to mislead government regulators.

You can tip your driver.

Uber, the ride-hailing conglomerate that said it would never, ever add tipping, finally said it would let riders start tipping their drivers via the app in three cities on Tuesday.

Lyft Inc, which is Uber's chief ride-services competitor in the United States, has always allowed drivers to collect tips through its app. Lyft said on Monday its drivers have collected a total of $250 million in tips during the company's lifetime.

There may be some awkwardness during the initial rollout of the tipping update, as both drivers and customers will need to have the latest versions of the Uber and UberEATS app.

Riders in those cities will be prompted to leave a tip of $1, $2, $5, or a custom amount when rating their driver following a ride.

"You've told us what you want, and now it's time we step up and give you the driving experience you deserve, because simply put, Uber wouldn't exist without you", the company said in an email sent to all of its USA drivers.

Uber has just announced significant changes to their business in an email sent to drivers and delivery partners. That change will roll out nationwide by the end of August, says Uber.

"A friend recently asked me, 'What went wrong?' and the answer is that we had not listened well enough to those who got us here ... our team and especially our drivers", wrote Camp in a Medium post titled "Uber's path forward". In metro Atlanta, the changes are expected to be in place by the end of July.
